A Unified Initial Alignment Method of SINS Based on FGO [PDF]
IEEE transactions on industrial electronics (1982. Print), 2022 The initial alignment provides an accurate attitude for strapdown inertial navigation system (SINS). By further estimating the IMU's bias and misalignment angle, the recursive Bayesian filter is accurate.

Results of the ontology alignment evaluation initiative 2022 [PDF]
, 2022 The Ontology Alignment Evaluation Initiative (OAEI) aims at comparing ontology matching systems on precisely defined test cases. These test cases can be based on ontologies of different levels of complexity and use different evaluation modalities. The OAEI 2022 campaign offered 14 tracks and was attended by 18 participants.

Initialization and Alignment for Adversarial Texture Optimization
, 2022 While recovery of geometry from image and video data has received a lot of attention in computer vision, methods to capture the texture for a given geometry are less mature. Specifically, classical methods for texture generation often assume clean geometry and reasonably well-aligned image data.

A New Analytic Alignment Method for a SINS
Sensors, 2015 Analytic alignment is a type of self-alignment for a Strapdown inertial navigation system (SINS) that is based solely on two non-collinear vectors, which are the gravity and rotational velocity vectors of the Earth at a stationary base on the ground. The
